Answer : 2 (two)
For every O ion, two Na ions are needed to balance charges.
Almost in every Physics books, momentum is denoted by P with small arrow(→) pointing towards right, placed on top of P.
I am guessing you asked about linear momentum.
Answer:
It has to overcome earth's gravity and have enough fuel to land on the moon at a slow enough speed
Answer:
The other end is called the south pole. When two magnets are brought together, the opposite poles will attract one another, but the like poles will repel one another. This is similar to electric charges. can you help me please asap Write at least 5 sentences on how you feel "War of the Worlds" will end. How will the problem of the aliens be fixed? Will Ray's son come back?

Explanation:
Given that:
angular frequency = 11.3 rad/s
Spring constant (k) = ![= \omega^2 \times m](https://tex.z-dn.net/?f=%3D%20%5Comega%5E2%20%20%5Ctimes%20m)
k = (11.3)² m
k = 127.7 m
where;
= 0.065 m
= 0.048 m
According to the conservation of energies;
![E_1=E_2](https://tex.z-dn.net/?f=E_1%3DE_2)
∴
![\Big(\dfrac{1}{2} \Big) kx_1^2 =\Big(\dfrac{1}{2} \Big) mv_2^2 + \Big(\dfrac{1}{2} \Big) kx_2^2](https://tex.z-dn.net/?f=%5CBig%28%5Cdfrac%7B1%7D%7B2%7D%20%5CBig%29%20kx_1%5E2%20%3D%5CBig%28%5Cdfrac%7B1%7D%7B2%7D%20%5CBig%29%20mv_2%5E2%20%2B%20%5CBig%28%5Cdfrac%7B1%7D%7B2%7D%20%5CBig%29%20kx_2%5E2)
![kx_1^2 = mv_2^2 + kx_2^2](https://tex.z-dn.net/?f=kx_1%5E2%20%3D%20mv_2%5E2%20%2B%20kx_2%5E2)
![(127.7 \ m) \times 0.065^2 = v_2^2 + (127.7 \ m) \times 0.048^2](https://tex.z-dn.net/?f=%28127.7%20%5C%20m%29%20%5Ctimes%200.065%5E2%20%3D%20v_2%5E2%20%2B%20%28127.7%20%5C%20m%29%20%5Ctimes%200.048%5E2)
